Application filed December 16. 1927.

My invention relates to curling irons.

it has for its object to provide a curling iron of improved construction whereby the life of the s n'ing, used in such an iron, is lengthened. A more specific object of my invention is to provide an improved construction and one especially adapted to use in electric curling irons and including improved spacing and cooling means between this spring and the iron pivot whereby breakage ot the spring adjacent the pivot is overcome. These and other objects and advantages of my improved construction will, however, hereinafter more fully appear.

In the accompanying drawings I have shown, for purposes of illustration, one embodiment which my invention may assume in. practice.

In these drawings,

Figure 1 is a central longitudinal sectional view of my invention applied to an electrical curling iron, the pivoted element being shown in a plurality of positions;

Fig. 2 is a sectional View on line 2-2 of Fig. 1;

Fig. 3 is an enlarged longitudinal sectional view of the pivoted element without its cooperating stationary element, and

Fig. l is a sectional Fig. 3.

in this illustrative construction I have shown a curling iron of usual construction, including an electrically heated member 1 and a usual pivoted member 2 pivoted on a transverse pin 3 on a clip i slidable on the member 1, a plate spring 5 being disposed between the member 2 and the member 1 in a well known manner and this spring 5 herein being associated with the pin 3 in an improved manner.

Herein, instead of having the spring 5 extend around the pin 3 in a curved portion or small radius in such manner as to bring itvery close to the pin, the curved portion of the spring 5 is enlarged in diameter, as at 6, and also spaced from the pin by a spacing member 7 which is of greater diameter than the pin and encircles the latter. Thus it will be noted that, since the portion 6 of the spring is disposed, and herein also supported substantially uniformly, at a greater distance from the pin in such manner that the bending strain. is prevented from being'localized at a point substantially halfway around the curve,

as heretofore, and since the spacing member 7 also acts to reduce the temperature of this portion of: the spring, the tendency" of this spring to break at that point is substantially decreased. Further, it will be noted that I have herein made the spacing member 7 in the form of a coiled spring disposed on the pin 3 between the upstanding ends or wings on the clip 4%, since I find that such a spring, in addition to forming an improved spacing and cooling means for the portion 6 of the plate spring 5., heretofore described, also acts even further to reduce the temperature of this portion of the plate spring and thereby further increase the life of the same, the reduction in temperature apparently being due to the 'convolutions of the coiled spring, which, due to their larger area and arrangement, act to dissipate the heat transmitted by the iron 1 and clip 4 to the pin 3.

As a result of my invention it is found that the wearing quality of the plate spring is substantially increased. Attention is also direct ed to theifact that the coiled spring 7 also acts to prevent loss or displacement of the stood that the invention is not limited there- I.

to but may be modified and embodied in various other forms without departing from its spirit or the scope of the appended claims.

VVhatI claim as new and desire to secure by Letters Patent is 1.
